(Who would have thought we'd need to be able to "make change" for a Penny...???)It is somewhat complicated to accept what you say, I will tell you because, the current market is quite volatile, what is sought is to replace the majority of this change in an encrypted form, that is, everything would be done with the cell phone, even in some countries this is already implemented, so it is difficult to accept it.
You understand me, but I respect what you say as always
